Developing BizTalk 2010 R2 with Visual Studio 2011??

Since a couple of days Microsoft enabled Windows Azure users to create Virtual Machines, which are based on BizTalk 2010 R2 CTP. This is great, because it offers those users to have a preview at that release, combined with some of the new related products, like SQL Server 2012 and .NET 4.5.

However, given the screenshot below, which was taken from the BizTalk 2010 R2 CTP Installation Wizard, it looks like Microsoft expected to release the next version of Visual Studio sooner :-)
